COAL-GHUIE CONSTRUCTION."

Application filednpril 7,

To all whom it may concern:

Be it known that I, F RANK E. IVAL a gGllllzen of theUnited States of America, residing at Detroit, in the-county of Wayne and State of Michigan, have invented certain new and useful Improvements in Goal-Chute Constructions,offwhich the following is a specification, reference being had therein to the accompanying drawings.

This invention relates generally to chutes and refers more particularly to those designed for use in the walls of buildings for introducing coal into the buildings.

' One of the essential objects of the invention is to provide a chute of this type that is adapted to be compactly folded or collapsed for shipment and that may be easily and quickly set up and installed in the wall of a building. 7

Another objectis to provide a strong and durable chute that is simple in construction and that can be manufactured at a comparatively low cost.

With the above and other objects in view the invention consists in certain novel features of construction, combinations and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a perspective view of a chute embodying my invention applied to a wall of a building; l

Figure 2 is a perspective view of the chute when folded for shipment.

Referring now to the drawing in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates a wall, preferably of a building having an opening 2 in which the chute 3 embodying my invention is preferably installed.

This chute preferably consists of a supporting frame 4 and a box-like body 5. The. frame 4: surrounds the opening 2 and is preferably secured to the outside ofthe wall While the body 5 extends through the opening 2 and is preferably formed of the top, bottom and side sections 6, 7 and 8 respectively. As shown, the top and bottom sections 6 and 7 respectively of the body are pivotally connected by suitable straps 9 to the parallel horizontal flanges 10 projecting inwardly from the inner side of the frame 4 and are preferably provided at their op- 1324. Serial No.- 704,889

posite ends with the parallel flanges 11 for engagement with the outer facesof theend sections 8-when the bOdy is set up, while the end, sections are preferably pivotally connected bvecorresponding straps 12 to. the parallel vertical, flanges 13 projecting inwardly from the framewbetween the horizontal flanges 10. Any suitable means such as bolts 14 may be used to connect the end sections 8 to the flanges 11 of the top and bottom sections of the body.

Thus, it will be apparent from the foregoing description that I have provided an extremely simple construction that is composed of relatively few parts which may be manufactured at a comparatively low cost and can be easily and quickly assembled and installed.

. In view of the pivotal connections between the sections of the body and the frame, the body may be readily folded or collapsed for shipment as shown in Figure 2 of the drawing. .Moreover, when the body is set up, the flanges l1 serve as reinforcing members and also prevent the end sections 8 from moving laterally.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that 5 I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is: on

1. In a chute, the combination with a sup porting frame, of a collapsible box-like body connected thereto.

2. In a chute, the combination with a sup porting frame, of a sectional box-like body, each section of the body being pivotally connected to the frame.

3. A chute comprisinga supporting frame having inwardly projecting flanges, a sectional body connected to said flanges, and means for connecting the sections of said body together.

4:. In a chute comprising a supporting frame, flanges projecting inwardly from the frame, a sectional body, and straps connecting thesections of the body to the flanges aforesaid.

5. In a chute, the combination with a supporting frame, of horizontal flanges projecting from the frame, vertical flanges projecting from the frame between the horizontal flanges, a sectional body, the end sections of the body being connected to the vertical flanges, the top and bottom sections of the body being connected to the horizontal flanges, and means for connecting the end sections to the top and bottom sections of said body.

6. In a chute, the combination With a supporting frame, of horizontal flanges projecting from the frame, vertical flanges projecting from the frame between the horizontal flanges, a sectional body, the end sections of the body being connected to the vertical flanges, the top and bottom sections of the body being connected to the horizontal flanges, flanges projecting from the top and bottom sections, and headed elements for securing said last named flanges to the end sections of said body.

7. In a chute, the combination With a supporting frame having inwardly projecting flanges, a sectional boxlike body, the sections of said body being pivotally connected to the flanges whereby the body may be collapsed for shipment.

8. The combination With a fixed support having an opening therethrough, of a chute having a frame surrounding the opening and rigidly secured to the support, and a collapsible box-like body carried by said frame adapted to close the opening 1n said support. In testimony whereof I aliix my signature FRANK E IVALL.
